This is new! Cagliari though of a solution to make citizens leave their own car at home. They're offering a car sharing service, you can 'borrow' a car so that you won't have to look for a parking space for hours on end when going downtown. In my opinion, this is also helping the environment and the city centre be less polluted. Share a car, with a guaranteed parking spot, instead of taking your own and pollute the air while you look for a parking space... What do you think?
